The New York Times has an article about sleep in other animals, and the possible evolutionary purposes of sleep, provoked by a researcher's hypothesis that sleep evolved as a way to allow neurons to recover from a hard day of learning. On a more academic note, Nature has a number of free access articles on aspects of sleep.

ScienCentral has an article about the habit study I mentioned a few days ago ( October 26, 2005), and another on new research claiming to have found a "dyslexia gene".

The newsletter for October has been uploaded at http://www.memory-key.com/newsletters/issue_68.htm. In this month's issue I discuss the idea that the brain is a muscle / exercise makes it stronger; advise about a new article on reading scientific text; and talk about my new novel!
